one of which notches is adapted to engage over l the lower flange of an I-beam and the other over a plasterers channel.

Other and further objects of the present invention reside in the provision of'a clip of the character stated in which are arranged a combination of parts for attaining the results sought by the foregoing objects.

The invention consists of the novel construction, hereinafter described and finally claimed.

The nature, characteristic features and scope of the invention Will be more fully understood from the following description taken in connection with the accompanying drawing forming g5 part hereof, and in which:

Fig. 1 is a View principally in longitudinal section of pre-cast ceiling slabs as supported from floor members;

Fig. 2 is a view in cross section of a pair of the 1.0 ceiling slabs shown in Fig. 1, as tied or coupled together;

Fig. 3 is a View in end elevation of one of the ceiling slabs; and

Fig. 4 is a View in perspective of one of the 45 ceiling slab supporting clips shown in Fig. 1.

For the purpose of illustrating my invention I have shown in the accompanying drawing one form thereof which is at present preferred by me, since the same has been found in practice to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized and that 55 my invention is not limited to the precise ar- 4rangement and organization 'of the instrumentalitiesnasherein shown and described.

Referring now to the drawing in detail.. and

with more especial relation rst to Figs. l to 4 introduce a plasterers channel I4 between a pair ofjfiioor members. Having `these conditions in mind it is of the essence of the ,present invention 15 that means be provided to properly suspend, with respect to the fiooring II, pre--ckast ceiling slabs I5 ofcementitious material. Each slab 'I5'has embedded therein a reinforcement comprising a ladder-likestructure made up of `angle-irons ITS 20 connecting which are cross-members Il, the terminus of each cross-member being bent over the tops of the angle-irons as at I8, see Fig. 2. Each slab I5 is provided at each end with spaced ngers I9 slightly bevelled. Each ceiling slab, 25 longitudinally considered, is grooved as at 20 to accept the fingers of metal clips best seen in Fig. 4. Each slab is also provided along its 1ongitudinal edges with spaced, vertically disposed slots 2|, across which the angle-irons I6 extend. 30 as best seen in Fig. 2. When the ceiling slabs are positioned side by side and end to end as clearly shown in Fig. 2, the wires 22 are employed for coupling together adjacent slabs, thus providing an interlock of reinforced parts throughout the width of the building. The tie-wires 22 are passed through apertures formed in the vertical bars of the angle-irons I6, best seen in Fig. 2. The longitudinal edges of the slabs are also provided With ribs 23 and grooves 24 to complete an 40 interlock of parts laterally.

The ceiling slabs are suspended from the oor members by means of a reversible clip, best seen in Fig. 4. Each clip is stamped from a single blank and comprises a vertically disposed plate 28 having opposed notched portions 29 and 30. In use the notched portion 29 of a clip is caused to engage over the lower ange of an I-beam l2, as best seen in Fig. 1. However, in case it is necessary, because the oor supports are not properly spaced, to make use of an auxiliary oor member 3| to support a small channel 32, then the notched portion 3D of a clip is caused to engage over the channel 32. In either case the ngers 33 of plate 28 are caused to engage over 65 5 and 34 are arranged at right angles to the plate 28 and are disposed inA different horizontal planes. 'Ihe plate 28gof a; clip {is provided withfopening 35 whereby the latter may be nailed'to place with sides thereof at' right angles thereto spaced fingers arranged in diierent planes for engaging ceiling slabs, said plate being horizontally notched Y along yits vertical edges in arplanerabove said lingers, of which notches optionally one is adapt- 4.
